Description

Feeding bottle with temperature display

Technical Field

The application relates to the technical field of temperature digital display, in particular to a temperature display feeding bottle.

Background

Along with the development of temperature digital display technology, the digital display technology is widely applied in the production and life fields, the temperature digital display technology is applied to the infant feeding bottle, the temperature of liquid in the feeding bottle can be reflected in real time through the temperature digital display technology, and compared with the temperature of the feeding bottle sensed by a person, the temperature sensing of the temperature digital display technology is more accurate.

The traditional temperature digital display feeding bottle mainly detects and displays the temperature of liquid in the feeding bottle through a feeding bottle cup sleeve (or a thermal insulation sleeve), a thermostat, a temperature measuring paste and other methods. The method for heating the milk bottle comprises the steps of arranging a cup sleeve capable of accommodating the milk bottle, arranging a temperature sensing circuit and a display screen in the cup sleeve, and displaying the temperature only by sleeving the cup sleeve outside the milk bottle. However, the user usually takes the feeding bottle with the temperature meeting the requirement out of the cup sleeve for use, so that the temperature of the liquid in the feeding bottle cannot be known in real time in the process of using the feeding bottle. The method of the thermostat is similar, and a user puts the feeding bottle into the thermostat to heat to a set temperature, and the feeding bottle needs to be taken out of the thermostat when in use, so that the temperature of liquid in the feeding bottle cannot be known in real time in the process of using the feeding bottle. For the method of 'temperature measuring paste', the temperature measuring paste is pasted on the outer wall of the feeding bottle for temperature detection and display, however, when the temperature measuring paste is used for feeding bottles with different materials or wall thicknesses, the displayed temperature has larger difference, namely the temperature error displayed by the temperature measuring paste is larger. Therefore, the existing feeding bottle temperature detection and display method cannot achieve real-time performance and accuracy of temperature detection and display.
